This is a potentially stupid question about Fuel Pressure Regulators:

Do all fuel pressure regulators have 1:1 when under boost? In other words, like the AEM adjustable F.P.R. that I have raises fuel pressure for every 1 PSI of boost pressure in the manifold, I am wondering if stock Honda F.P.R.'s do this. If not then do factory turbo cars have 1:1 regulators (Turbo Eclipse for example)

Please expand upon this.

 

the only thing thats not 1:1 is a boost dependant fuel pressure regulator like the vortech FMU, jackson allso makes one along with cartech. The regualr B&M AFPR and the like are all 1:1
the stock honda is 1:1 and turbo eclipse and other factory turbo cars make up for fuel in the ecu not a piggy back FMU

I am absolutely aware of how factory turbo cars deliver fuel, of course not with an FMU.

Thanks for the information though.

 

Than what is your question?

Just whether or not all FPR's are 1:1 under boost.

unless its a rising rate FPR, yes. On stock cars, yes, on stock turbo vehicles, yes its 1:1 stock honda, 1:1 stock awd talon, 1:1.
